RADIATOR FOR AUTOMOBILES.

Patented Nov.. 18, 1919.

Application filed January 19, 1917. Serial No. 143,336.

To all whom t may concern:

Be it known that ll, EDWARD H. ELLIsoN, a citizen of the United States, residing at Jamestownin the county of Chautauqua, State of New York, have invented certain new and useful Improvements in Radiators for Automobiles, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

rlhe invention relates to new and useful improvements in radiators for automobiles, an more particularly to the means for securing the radiator core to the frame at the upper and lower water tanks.

lin connection with radiators for heavy trucks, it has been customary to provide a cast iron upper and lower-tank, and also east iron side memberswhich are joined to the tank so as to form a rigid frame. The radiator core is attached to this rigid frame. lit has also been customary to grind the surface of the cast iron where the core is attached thereto, and it is a well-known fact that ground surfaces are not always straight and true, and furthermore it often occurs that there are slight differences in the'distance between the upper and lower tanks and also slight dilferences in the size of one radiator core from another.'

An object of the present invention is, therefore, to provide a flexible means for connecting the radiator core to the rigid frame, which flexible means readily allows the radiator core to be connected to the frame even though there be slight variations in the sizes of the cores or the distance between the tanks or slight unevenness in the surface to which the core is attached.

A further object of the invention is to pro- Vide'a connecting means for connectin a core to the rigid frame, which connectlng means includes rigid devices secured to the core and a flexible member which is also secured to these rigid devices and to the rigid frame.

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.

lin the drawings, which show by Way of illustration one 4embodiment of the invention Figure l is a front view of a section of an The radiator includes a cast iron upper tank and a cast iron lower tank which are connected by cast iron sides, and when these parts are bolted together they form a ver rigid frame which is capable of withstan ing the vibrations that are inherent in solid tire motor trucks. A convenient and inexpensive means of preparingthe surfaces of the rigid frame to which the core of the radiator is attached is by grinding parts of the surfaces on surface rinders. It is a wellknown fact that surfaces ground thus are not exactly straight and true. It is also well-known that there is a slight difference in the distance between the upper and lower tanks at one side of the radiator from that at the other side of the radiator, and also that the radiator cores vary in'size no matter how carefully 4they may be manufactured.

The present invention is directed particularly to the manner of .connecting the radiator core to the radiator frame. A perforated metal plate is attached to the lower tank, and this forms a support for the radiator core. Extending about the sides and ends of the radiator core at the lower end thereof are metal strips and also lflexible strips preferably of copper or low brass. These strips are secured togetherand sol- ,dered to the radiator core, andthe flexible strip is clamped to the rigid frame. At the upper end of the core there isl a perforated plate, also metal strips' extending along the sides and "ends of the radiator core, andaflexible strip. These strips and the plate are riveted or otherwise secured together and are also soldered or otherwise secured to the radiator core with the flexible strip extending outwardlyfrom the sides and ends of the core. This flexible strip is clamped to formed of cast iron. Theseitanks are bolted to cast iron side frames, one of which is indicated at 3 in the drawings. This forms a rigid frame within which a radiator` core, indicated more or less diagrammatically at 4, is located. Connected to the lower tank is a perforated metal plate 5, the perforations being indicated at 6. This plate extends from side to side and end to end of the lower tank and is 'secured thereto by clamping bolts 7.

Secured to the lower end of the radiator core along the sides and ends thereof are metal strips 8, and secured to these metal strips and also to the radiator core are flexible strips 9 which are, as above noted, preferably formed of copper or low brass. The

strip v9 and the strips 8 may be riveted together or soldered together, and they-may also be soldered to the radiator core, the essential features consisting in rigidly secur- 4 ing. 'the strips together so as to form a rigid frame at the lower end of the radiator core vwhich is connected through this flexible strip with the rigid frame of the radiator.

The flexible strip, indicated at 9 in the drawings, is clamped against the upper face of the plate 5 by the clamping bolts 7. Theseclamping bolts pass through flanges on the side frames, and also through a strap 10 which extends from one side frame to another. The flexible strips 9 are provided with openings 11 through which the bolts 7 pass. A suitable packin or gasket, indicated at 12, may be place between the plate 5 `and the flange of the lower tank. It will be understood that the radiator core rests freely on the plate 5 and is secured at its bottom tothe radiator frame solely through these flexible strips 9.

At the upper end of the radiator core there are metal strips 13-13 which extend along the sides and ends of the radiator core, and on top of these strips are flexible stri s 14, and on top of the strips 14 is a per orated metal plate 15. The strips 13 and 14 and the metal plate 15 are all riveted or soldered together and are also soldered or otherwise secured to the radiator core, thus forming a r1g1d frame for the upper end of the core. The metal plate 15 and the strips i :13 mai be of any desired metal, but I prefer to ma e the flexible strips 14 of copper or lo w brass, as described above in connection wlth the Strips 9. The flexible strips 14 are secured to the upper tank by bolts 16. The flexible strips 14 are provided with elongated openings 17 through which the bolts 16 pass. The flanges on the side frames are clamped lagainst this strip and a strip 18 extending from one side frame to the other is also clamped against the flexible strip. A su1table pac ring or gasket is placed between the strips 14 and the-flange of the tank to which it is attached.

As above noted, it is desirable to grind the surfaces of the flanges on the tanks, and these surfaces are more or less uneven, and it sometimes happens that the distance between the flanges on the tank at one side of the radiator is greater than at the other side of the radiator frame. After the edge of the tank and both ends of the side piecesl cast iron side pieces are put in place, and the bolts 7 are drawn up tight, thusV securing the side pieces to the lower tank and the flexible strip 9 to the lower tank. The upper tank is then placed on the side castings,

and said side castings if necessary sprung into`place and the bolts 16 inserted in the openings in the side plates and upper tank. The core, however, is not sprung so as to cause any strain whatever on the same, but is allowed to remain in its natural position7 and if it tilts either toward the front or the back the oblong holes 17 in the strip permit of this tilting. The bolts 16 are then drawn tight, and this firmly clamps the upper end of the radiator core. The drawinor up of the bolts securing the parts of the frame in no way transmits any strain upon the radiator core even though the plate 5 -may be twisted or bent when the bolts are drawn tight. The soldered joints between the frames attached to the radiator core will maintain their maximum strength as they cannot be broken loose at any short interval owing to the flexibility of the strips which secure the radiator core to` the lrigid frame, but will have to break loose on a whole side at once.

Itis obvious that minor changes in the details of construction and the arrangement of parts may be made when desired w1thout departing from the spirit of this invention as set forth in the appended claims. Y Having thus described the invention, what is claimed as new is 1. In an automobile radiator, the combination of a rigid frame including upper and lower tanks and a radiator core, means forming a rigid frame at the u per and lower portions of said core, a flexi le metal strip secured thereto and means connecting said strip to said upper and lower` tanks.

2. A radiator for automobiles including upper and lower tanks, side frames rigidly connected to` said upper and lower tanks, a ,supporting plate connected to the upper face of the lower tank, a radiator core supported by said plate, said radiator core having rigid metal frames at the upper. and lower ends thereof, and flexible strips connected to said rigid frames, said flexible strips being connected respectively to the upper and lower tanks, said upper flexible strips having elongated openings through which the securing bolts pass whereby said radiator core may be secured in place without tilting or straining the same.

3. A radiator for automobiles including upper and lower tanks, side frames rigidly connected to said tanks, a supporting plate connected to the upper face of the lower tank, a radiator core extending from the lower tank to the upper tank, rigid metal strips, and -flexible metal strips secured to .the lower end of said radiator core and forming a rigid frame therefor, said flexible metal strips being secured to the lower tank, rigid metal strips, and flexible strips connected to the upper end of said radiator core and forming a rigid frame therefor,
